Hydraulic Filters: Critical Equipment for Maintaining the Health of the Hydraulic System

Cleanliness and efficiency in hydraulic systems are vital for equipment longevity. This is where hydraulic filters come into play. These small but critical components ensure the long-lasting operation of your machine by removing dirt, metal particles, and contaminants from the system.

What is a Hydraulic Filter?

A hydraulic filter is a device that filters hydraulic oil from the system, removing particles and impurities. Clean oil ensures accurate and efficient transmission of system pressure, minimizing wear and failures.

Basic parts:

  • Filter element (paper, metal or synthetic material)
  • Filter body
  • Input/output connections
  • Gauge and bypass valve (optional)

Types of Hydraulic Filters

Hydraulic filters are produced in different types depending on their intended use:

  1. Suction Filters are placed at the → Pump inlet, prevent the system from drawing dirty oil.
  2. Return Filters → Cleans the oil in the system in the return line.
  3. Pressure Filters → Filters oil from the system at high pressure and protects critical equipment.
  4. Fine Filters → Provide extra protection against microparticles.

Advantages of Using Hydraulic Filters

  • Extends equipment life → Protects pumps, valves and cylinders.
  • It reduces malfunctions → minimizes interruptions caused by dirt in the system.
  • Increases efficiency → Clean oil reduces energy losses.
  • Facilitates maintenance → System performance is maintained with filter replacement and cleaning.

Things to Consider in Hydraulic Filter Selection

  1. Filtration rating (micron) → How many fine particles will be filtered out?
  2. The flow capacity should be compatible with the oil flow required by the → system.
  3. Material and durability→ Should be suitable for heavy-duty industrial or outdoor applications.
  4. Indicator and bypass option → There should be a mechanism that will show filter clogging in time.

Hydraulic Filters - Frequently Asked Questions (FAQ)

  1. What is a hydraulic filter and what does it do?
    Hydraulic filters remove oil from hydraulic systems, preventing dirt, metal particles, and other impurities from damaging the system. Thus, it extends the efficient operation of the system and the equipment life.
  2. Why are hydraulic filters important?
    Dirty oil causes wear and malfunctions in pumps, valves and cylinders. Filters keep the system clean, reducing maintenance costs and reducing downtime.
  3. What are the types of hydraulic filters?
  • Suction filter: Cleans the oil before the pump, ensuring the pump is protected.
  • Return filter: Cleans the oil circulating in the system, ensuring overall cleanliness.
  • Pressure filter: Resistant to high pressure, ensuring oil is cleaned before sensitive equipment.
  1. How long should the filter replacement period be?
    Filter replacement varies based on the system's operating hours and manufacturer recommendations. It is generally recommended to perform 500-1000 operating hours or during an oil change. Filters with pressure gauges or pollution indicators should be replaced when a warning occurs.
  2. What happens if the filter is clogged?
    A clogged filter can prevent oil flow, leading to reduced performance and wear on pumps and cylinders. Many filters have a bypass valve; This valve passes oil directly when the filter is clogged, but in this case the cleaning function is lost.
  3. What should be considered when choosing a hydraulic filter?
  • Micron value of the filter  (cleaning sensitivity of the oil)
  • Compliance with system pressure and flow rate
  • Durability and material quality
  • OEM or system manufacturer recommendations
  1. How to maintain a hydraulic filter?
  • Regular visual inspection and pressure differential monitoring
  • Measuring the cleanliness of the oil regularly
  • Filter replacement according to manufacturer's recommendation
  1. Can I replace the filter myself?
    Yes, most hydraulic filters can be replaced by the user. However, safety precautions should be observed in closed pressurized systems to avoid damaging the system.
